Laravel5.4当图像可读时不可读的异常

Question

我正在学习Laravel5.4的干预图像包。我在“公共/图像”文件夹中存储了一个图像。

我按照干预页面上的说明安装了图像:将干预添加到我的composer.json文件、composer.json更新、更新了我的config/app文件以及composer.json autoload。

• 当作为图像直接访问时(下面代码块中的printf语句)显示图像。
• 使用make方法，我在AbstractDecoder.php中得到了一个AbstractDecoder.php。

是否有人看到我在代码中做错了什么，或者可能在安装过程中错过了一个步骤？

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Intervention\Image\Facades\Image;

class TestController extends Controller
{
    public function imagetest()
    {
        printf('<img src="/images/j6.jpg">'); //correctly displays image on page

        $img = Image::make("/images/j6.jpg")->resize(300, 200); //throws the error
        return $img->response('jpg');
    }
}

下面是"printf“图像后面页面上的错误块的牵头部分：

Whoops, looks like something went wrong.

Answer 1

您需要从图像标记中提供filesystem.Judging中图像文件的完整路径，图像应该位于webroot的images文件夹中。你可以做到这一点。

$imagePath = public_path('images/j6.jpg');
$img = Image::make($imagePath)->resize(300, 200);
